About the Basic Calculator

Type expressions like 50% of 80 + sqrt(2)^2 - sin(30). Supports constants pi, e, functions sqrt, abs, round, floor, ceil, ln, log10, sin, cos, tan, asin, acos, atan, operators +, -, *, /, ^, mod, percent postfix %, and the keyword of (e.g., 50% of 80).

  • DEG/RAD toggles trigonometric input/output convention.
  • Percent x% equals x/100. So 20% of 150 = 0.2 * 150.
  • Two-argument functions: min(a,b), max(a,b), mod(a,b), pow(a,b).
